 using system;  using system.collections.generic;  using system.linq;  using system.text;   namespace consoleapplication305 { class program {     static void main(string[] args)     {         trip = new trip();         console.writeline(a);      }      class trip     {         int distancetraveled;         double costgas;         int numbergallon;         int mpg;         double cpm;          public int distancetraveled         {                         {                 return distancetraveled;             }         }         public double costgas         {                         {                 return costgas;             }         }         public int numbergallon         {                         {                 return numbergallon;             }         }          public trip()         {             distancetraveled = 312;             costgas = 3.46;             numbergallon = 10;          }          public void milespergal()         {             mpg = distancetraveled / numbergallon;         }          public void costpermile()         {             cpm = costgas * mpg;         }          public override string tostring()         {             return string.format("the distance traveled is...{0} \nthe cost per gallon of gasoline is... {1} \nthe amount of gallons were... {2} \nthe miles per gallon attained were... {3} \nthe cost per mpg were... {4}", distancetraveled, costgas, numbergallon, mpg, cpm);         }     } } 

}

if understand question correctly, should work you:

class trip {     int distancetraveled;     double costgas;     int numbergallon;     int mpg;     double cpm;      public int distancetraveled     {                 {             return distancetraveled;         }     }     public double costgas     {                 {             return costgas;         }     }     public int numbergallon     {                 {             return numbergallon;         }     }      public trip()     {         distancetraveled = 312;         costgas = 3.46;         numbergallon = 10;         mpg = milespergal();         cpm = costpermile();     }      public int milespergal()     {         return distancetraveled / numbergallon;     }      public double costpermile()     {         return costgas * mpg;     }      public override string tostring()     {         return string.format("the distance traveled is...{0} \nthe cost per gallon of gasoline is... {1} \nthe amount of gallons were... {2} \nthe miles per gallon attained were... {3} \nthe cost per mpg were... {4}", distancetraveled, costgas, numbergallon, mpg, cpm);     } }
